Cancer immunotherapy has drawn increasing attention in recent years. Although still at its infancy, it has brought hope to many cancer patients. Exploring the anti-tumour activities of a rare immune cell type in the human body is the focus of a research project led by a biomedical scientist and her research team at City University of Hong Kong (CityU). The research findings will provide insights into designing new generations of cancer immunotherapy and vaccine against different cancers.
Toilet hygiene has once again aroused public concern during the outbreak of the novel coronavirus epidemic. According to a study done by City University of Hong Kong (CityU), airborne aerosol droplets created in flushing might rise up to a metre if the toilet was not covered, and the pathogens embedded in the droplets can potentially spread and affect toilet users’ health.
Protein and DNA (deoxyribonucleic acid) may sound familiar to everyone, but RNA (ribonucleic acid) is probably another story. In fact, RNA plays a pivotal role in many aspects, such as decoding the genetic codes stored in DNA and producing protein. Dr Kwok Chun Kit, Assistant Professor from the Department of Chemistry at City University of Hong Kong (CityU), is devoted to studying RNA. He hopes to reveal the structure of a specific type of RNA and its interactions in cells, as well as its biological functions and mechanism, in order to develop chemical and molecular tools for diagnostic and therapeutic applications.
New droplet-based electricity generator: A drop of water generates 140V power, lighting up 100 LED bulbs
Generating electricity from raindrops efficiently has gone one step further. A research team led by scientists from the City University of Hong Kong (CityU) has recently developed a droplet-based electricity generator (DEG), featured with a field-effect transistor (FET)-like structure that allows for high energy-conversion efficiency and instantaneous power density increased by thousands times compared to its counterparts without FET-like structure. This would help to advance scientific research of water energy generation and tackle the energy crisis.
A study by City University of Hong Kong (CityU) reveals for the first time that schema-like learning can foster the growth and regeneration of brain myelin, thereby enhancing the learning and memory capacity. This has helped shed light on revealing the pathological mechanisms of central myelin diseases such as multiple sclerosis, cerebral ischemia, chronic recurrent pain, irritable bowel syndrome (IBS), severe depression and Alzheimer's disease.
High strength and high ductility are often mutually exclusive properties for structural metallic materials. A recent study led by the City University of Hong Kong (CityU) revealed a new strategy to overcome this trade-off dilemma. Aided by molecular dynamics simulations, the research team developed a hierarchical nanostructured aluminium alloy composed of amorphous-nanocrystalline structures. This new aluminium alloy achieves the highest strength and high ductility of its kind so far. It can be applied to micro-electromechanical systems (MEMS) for flexible wearable devices in the future.
A recent research led by City University of Hong Kong (CityU) has discovered that the ultrathin gold nanoribbons with unique hexagonal (4H type) crystal phase shows “liquid-like” behaviour under heating, but its hexagonal crystalline structure remains stable. This provides insight into the thermal stability of this new type of metallic nanomaterials and facilitates the development of practical applications in the future.
A new supramolecular silicone coating: damage-healable, oil-repellent and adhesive to various materials
A research project led by City University of Hong Kong (CityU) has invented a new supramolecular silicone (DOSS) coating with inherent damage-healing and oil-repellent properties which can be adhesive to various materials. The research team managed to overcome the existing materials’ limitations by molecular engineering. They envision that it can be utilized in self-cleaning, antifouling, catalysis, energy storage and heat transfer with broad applications in the energy, environmental, and biomedical aspects.
Sensing a hug from your friend through a video call with him/her may become a reality soon. A joint-research team consisted of scientists and engineers from City University of Hong Kong (CityU) and Northwestern University in the United States has developed a skin-integrated virtual reality (VR) system, which can be controlled and powered wirelessly. The innovation has great application potential in communications, prosthetic control, and rehabilitation, as well as gaming and entertainment.
A team of researchers from City University of Hong Kong (CityU) and Karolinska Institutet has recently developed a new protein that can help increase the targeting accuracy in the genome editing process. It is believed that it would be useful for future gene therapies in human which require high precision.
